Repeated observations of numbers of bicycles and empty spaces available at each of the docking stations that comprise Boston, Cambridge and Somerville's primary bicycle sharing system (BSS), currently known as Hubway, between 2013 (shortly after launch) and late 2018 (no data for December 2017/January 2018). The observations are collected from the system's data feed at generally 2 minute intervals. The Boston system partially shuts down for winter.

Summary observations of the numbers of bicycles reported as being available in the system, at generally the same frequency as the individual docking station observations.

Locations, operator IDs and names of former and current docking stations in the system.

A summary analysis and graph, showing how the numbers of bicycles available has varied with time, based on this data.

Notes: The data is supplied with UK (GMT or BST) timestamps. Researchers would need to convert this to local time, bearing in mind that the UK observes summer time with different switchover dates than the US.
